Perspex can be used as a substitute of glass. Its monomer is__________________?
Correct answer: A. Methyl methacrylate
- A. Methyl methacrylate
- B. DMT
- C. Butadiene
- D. Tetrafluoroethylene
Explanation
Perspex is polymethyl methacrylate, formed by polymerising methyl methacrylate monomer. The other choices are monomers for different polymers, such as butadiene for synthetic rubber and tetrafluoroethylene for PTFE.
